Human hair loss symptoms or associated with a specific gene

Japanese scientists have found that periodic hair removal by mice may be caused by a lack of genes.　　This conclusion may also be used to explain human hair loss.　　The study, led by Zuohexian, a research paper published in the Proceedings of the National Academy of Sciences at the National Institute of Genetics, was headed by Mei Zi, Reuters reported 26th. The scientists managed to reduce a gene called Sox21 in mice and then observe. "These mice were born 11 days later and began to lose their hair, starting from the head to the tail," the paper wrote. 20 days to 25 days after birth, the hairs eventually fall out, including whiskers. Interestingly, the new hairs will grow again after a few days, but continue to be waxed.　　"The hair removal process lasted more than two years. The scientists found that the glands in the vicinity of the hair follicles increased during these rats ' hair removal. "This gene may be related to the mutation of the stem cells that form the hair outer layer," the paper wrote. "Scientists found the same gene in human skin samples. "This proves that the SOX21 gene may be associated with some human hair loss. "(AP)
